This article describes a standard scheme for representing IPA
transcriptions in ASCII for use in Usenet articles and email.  The
following guidelines were kept in mind:

        o It should be usable for both phonemic and narrow phonetic

        o It should be possible to represent *all* symbols and
          diacritics in the IPA.

        o The previous guideline notwithstanding, it is expected that
          (as in the past) most use will be in transcribing English,
          so where tradeoffs are necessary, decisions should be made
          in favor of ease of representation of phonemes which are
          common in English.

        o The representation should be readable.

        o It should be possible to mechanically translate from the
          representation to a character set which includes IPA.  The
          reverse would also be nice.

In order to be able to represent a wide range of segments while making
common segments easy to type, we allow more than one representation
for a given segment.  Each segment has an "explicit" representation,
which is a set of features between curly braces ("{" and "}").  Each
feature is represented as a three letter abbreviation taken from a
standardized set.  The phoneme /b/ (a voiced, bilabial stop) could be
represented as /{vcd,blb,stp}/.  A first cut at the feature set
appears in appendix A below.

The word "tag" could thus be represented phonemically as
and phonetically as

This works, but it's a bit of a pain.  To simplify transcription, we
allow an "implicit" representation for a segment which consists of a
(generally alphabetic) symbol followed by diacritics.  Thus /b/ stands
for /{vcd,blb,stp}/.  Case is significant (/n/ and /N/ are different
segments).  The segment symbols are given in appendix B below.

The word "tag" can thus be represented phonemically as

The diacritics for a segment are represented between angle brackets
("<" and ">") and consist of symbols or features.  (In the common case
where the diacritic symbol is a single character which does not encode
a segment, the brackets may be removed.)  The features which the
diacritics map to override those of the segment.

The word "tag" thus becomes narrowly

Some diacritic symbols encode more than one feature set.  Which one is
meant should be apparent from context.  For example, "." stands for
"{rnd}" when attached to a vowel, but "{rfx}" when attached to a

Clicks are common to many languages (especially in Africa), but there
is no IPA diacritic that means "click".  Rather than use up several
characters for clicks (which are infrequent in the languages most
often discussed), we instead use the diacritic "!" after the
homorganic unvoiced stop.  Thus /t!/ (= /t/ = /{alv,clk}/) is the
sound commonly written "tsk" and used in English to show disapproval.

The complete set of diacritic symbols appears in appendix C below.
Appendices D and E contain representations of segments more or less
ordered by feature (appendix D in tabular form, appendix E as a list).
Appendix F contains a list of all of the ASCII characters and the uses
they have been pressed to.

For transcription of any specific language a group can by convention
alter the character mappings (as an example, for Spanish /R/ may be
better used to represent /{alv,trl}/ than /{mid,cnt,rzd,vwl}/).  An
author may also press a little used symbol (for the language under
consideration) into service to highlight a distinction.  Such an
alteration should be made explicitly to avoid confusion.

The diacritics "+" and "=" and the segment symbols "$" and "%" are
explicitly left unspecified so that they can be used to mark
language-specific features (that are otherwise cumbersome to mark).
Such symbols can be assigned either by convention for a specific
language or in an ad-hoc manner by an individual author.

Stress marks are prepended to the syllable they attach to.  "'"
signals primary stress, "," signals secondary stress.  Spaces should
be employed to separate words (cliticized words may be written
unseparated).  When discussing single words, it may be helpful to
insert a space before each syllable that doesn't carry a
suprasegmental marker.

The "I hear the secretary" for an American might be something like
        /aI hir D@ 'sEkrI,t&ri/
while to an Englishman it might be more like
        /aI hi@ DI 'sEkr^tri/
Transcribing tone is harder.  Here's an attempt. For register tone
languages (e.g., Hausa, Navajo), numbers should be used with one being
the lowest.  Thus in Navajo, "1" is low tone and "2" is high.  In
Yoruba "1" is low, "2" is mid, and "3" is high.  The language's
"default" tone need not be specified.  For contour tone languages
(e.g., Mandarin, Thai), there is generally a numeric system in place
(Mandarin: "1" is high, "2" is rising, "3" is falling rising, "4" is
falling).  The tone indication should follow the syllable (vowel?).

The symbol "#" is used to represent a syllable or word boundary.

Appendix B.  Segment Symbols

This table lists the symbol, the associated feature set, and the
Unicode character code and name for the corresponding IPA character.
In some cases (e.g., /I/) there are multiple IPA characters in use for
the segment.  I have listed both.  In some cases (e.g. /j/), the IPA
symbol seems to be ambiguous (generally between an approximant and the
homorganic voiced fricative).

The entries marked with "??" are those that I am least sure of.  When
I have listed more than one possibility for a symbol, the first is my
current preference.

To aid English speakers in using the phonetic transcription, this
document describes the mapping onto a standard American dictionary
transcription system for sounds that commonly occur in the English
language.  When it differs from the symbol used, I've also included a
description of the IPA symbol for the benefit of non-Americans.

The table is taken from	the 'Pronunciation Symbols' page of
Merriam-Webster's New Collegiate Dictionary.  In the examples, the
letters which spell the sound are bracketed by '<...>'.

Note that this only describes a small subset of the transcription
system.  There are far more sounds (used in other languages) and
nuances of sound that can be captured.  See the document describing
the full standard for complete details.

Phonemic (broad) transcriptions are bracketed by '/.../'.  Phonetic
(narrow) transcriptions are bracketed by '[...]'.  Syllables that
carry primary stress are preceded by "'".  Syllables that carry
secondary stress are preceded by ",".  When giving the transcription
of a single word, spaces are generally inserted between syllables
(often omitted before syllables that have stress marks).  When giving
the transcription of a multi-word utterance, it is common to put
spaces between words and omit them between syllables.

/@/: schwa (upside-down 'e').
     Used in both unaccented ('b(a)nan(a)', 'c(o)llide', '(a)but'),
     and accented ('h(u)mdr(u)m', 'ab(u)t') contexts.

     The IPA symbol is a schwa.

     [British speakers often have different vowels in these two
     contexts.  The accented one is further back and is written /V/.
     Its IPA symbol is a 'wedge' or upside-down 'v'.]

/l-/, /n-/, /m-/, /N-/:
     Superscript schwa preceding consonant.
     As in 'batt(le)', 'mitt(en)', 'eat(en)'.  Signifies that the
     consonant is pronounced as a syllable by itself.

     The IPA symbol is a vertical bar below the consonant.

/R/: shwa followed by 'r'.
     'op(er)ation', 'f(ur)th(er)', '(ur)g(er)'.

     The IPA symbol is a schwa with a hook.

/&/: short a.
     'm(a)t', 'm(a)p', 'm(a)d', 'g(a)g, 'sn(a)p', 'p(a)tch'.

     The IPA symbol is an 'a-e' digraph.

/eI/: long a ('a' with bar above).
     'd(ay)', 'f(a)de', 'd(a)te', '(a)orta', 'dr(a)pe', 'c(a)pe'.
/A/: a with diaeresis (two dots) above.
     'b(o)ther', 'c(o)t', and, with most American speakers,
     'f(a)ther', 'c(a)rt'.

     The IPA symbol is a script 'a'.

/a/: a with dot above.
     'f(a)ther' as pronounced by speakers who do not rhyme it with

/AU/: a followed by u with dot.
     'n(ow)', 'l(ou)d', '(ou)t'.

/b/: '(b)a(b)y', 'ri(b)'.

/tS/: ch.  The dictionary notes "(actually, this sound is \t\ + \sh\)"
     '(ch)in', 'na(tu)re' (/'neI tSR/).

     In IPA transcription, this is sometimes spelled as 'c with hacek'.

/d/: '(d)i(d)', 'a(dd)er'.

/E/: short e.
     'b(e)t', 'b(e)d', 'p(e)ck'.

     The IPA symbol is a lower-case epsilon.  It is sometimes spelled
     with a small capital E.

/i/: long e ('e' with bar above).
     'b(ea)t', 'nosebl(ee)d', '(e)venl(y)', '(ea)s(y)'.

/f/: '(f)i(f)ty', 'cu(ff)'

/g/: '(g)o', 'bi(g)', '(g)ift'.

/h/: '(h)at', 'a(h)ead'.

/hw/: '(wh)ale' as pronounced by those who do not have the same
     pronunciation for both 'whale' and 'wail'.

/I/: short i.
     't(i)p', 'ban(i)sh', 'act(i)ve'.

     The IPA symbol is a small capital I or a lower-case iota.

/aI/: long i ('i' with bar above).
     's(i)te', 's(i)de', 'b(uy)', 'tr(i)pe'.

/dZ/: j. The dictionary notes "(actually, this sound is \d\ + \zh\)"
     '(j)ob', '(g)em', 'e', '(j)oin', '(j)u(dge)'.

/k/: '(k)in', '(c)oo(k)', 'a(che)'.

/x/: k with bar below.
     Geman 'i(ch)', 'bu(ch)'.

/l/: '(l)i(l)y', 'poo(l)'.

/m/: '(m)ur(m)ur', 'di(m)', 'ny(m)ph'.

/n/: '(n)o', 'ow(n)'.

/~/: superscript 'n'.
     "indicates that a preceeding vowel or diphthong is pronounced
     with the nasal passages open as in French 'un bon vin blanc' /W~
     bo~ va~ blA~/"

     The IPA diacritic is a tilde above the vowel.

/N/: eng ('n' with a tail).
     'si(ng)' /sIN/, 'si(ng)er' /'sIN R/, 'fi(ng)er' /'fIN gR/,
     'i(n)k' /iNk/

     The IPA symbol is an eng.

/oU/: long o ('o' with bar above).
     'b(o)ne', 'kn(ow)', 'b(eau)'.

/O/: 'o' with dot above.
     's(aw)', '(a)ll', 'gn(aw)'.

     The IPA symbol is a small open 'o' or upside-down 'c'.

/W/: o-e digraph
     French 'b(oeu)f', german 'H(o:)lle.

     The IPA symbol is an o-e digraph.

/Oi/: 'o' with dot above followed by 'i'.
     'c(oi)n', 'destr(oy)'.  [The dictionary also lists 's(awi)ng',
     but I pronounce that as two separate syllables /'sO IN/.]

/p/: '(p)e(pp)er', 'li(p)'.

/r/: '(r)ed', 'ca(r)', '(r)a(r)ity'.

/s/: '(s)our(ce)', 'le(ss)'.

/S/: sh.
     '(sh)y', 'mi(ssi)on', 'ma(ch)ine', 'spe(ci)al'.

     The IPA symbol is an esh: a tall, pulled 's' or long, barless 'f'.

/t/: '(t)ie', 'a(tt)ack'.

/T/: th.
     '(th)in'. 'e(th)er'.

     The IPA symbol as a lower-case theta.

/D/: 'th' with bar below.
     '(th)en', 'ei(th)er', '(th)is'.

     The IPA symbol is an eth, sort of a script 'd' with the bar crossed.

/u/: 'u' with diaeresis (two dots) above.
     'r(u)le', 'y(ou)th', 'union' /'jun j@n/, 'few' /fju/.

/U/: 'u' with dot above.
     'p(u)ll', 'w(oo)d', 'b(oo)k', 'curable' /'kjUr @ b@l/.

     The IPA symbol is a small letter upsilon.  A small capital U or
     closed lower-case omega is also used.

/y/: u-e digraph.
     German 'f(u:)llen', 'h(u:)bsch', French 'r(ue)'.

/v/: '(v)i(v)id', 'gi(ve)'.

/w/: '(w)e', 'a(w)ay'.

/j/: '(y)ard', '(y)oung', 'cue' /kju/, 'union' /'jun y@n/;

/(cons);/: superscript 'y' following consonant;
     "indicates that during the articulation of the sound represented
     by the preceding character, the front of the tongue has
     substantially the position it has for the articulation of the
     first sound of 'yard', as in French 'digne' /din;/."

     The IPA diacritic is a superscript 'j' following or hook below
     the consonant.

/ju/: '(you)th', '(u)nion', 'c(ue0', 'f(ew)', 'm(u)te'.

/jU/: 'c(u)rable', 'f(u)ry'.

/z/: '(z)one', 'rai(se)'.

/Z/: zh.
     'vi(si)on', 'azure' /'aZ R/.

     The IPA symbol is a yogh: like a flat-topped '3' lowered so that
     the top is the height of that of a 'z'.
